How to connect STM32L4R9I and STM32L152CC6. Access to Multi-function Expander

[HNguy.1611]

Hello,

Lately, i have been working on STM32L4R9I Disco. i am trying to figure out the way to connect and control peripheral using MFX function on the board.

Does anyone have any idea about MFX function?

Thank you very much

MFX embed various custom fonctionalities, depending on the discovery, it could be additional GPIOx, interrupt generation and power measurement.

You could probably found how it is controlled in our examples by looking to related HAL SW demo sources.
